SECTION 1

Why Evidence Matters

Imagine your friend says, "That movie was the best one this year." You might ask, "Why do you think so?" Your friend's reasons are evidence — the proof that backs up their opinion. People have cared about evidence for thousands of years, because without it, anyone can say anything and nobody can tell what is really true.

On the ISEE, you will read passages where the author makes a claim (a main point or argument). Then a question will ask you to find the sentence or detail in the passage that proves the claim is true. This is one of the most important skills you can have, both on test day and in everyday life.

~350 BC • Aristotle and Rhetoric

The Greek philosopher Aristotle taught that every good argument needs logos — logical proof and evidence to convince your audience.

1620 • The Scientific Method

Francis Bacon promoted the idea that scientists must collect evidence through experiments before making conclusions.

1890s • Modern Standardized Testing

Schools began using reading comprehension tests that required students to point to specific text evidence, not just give opinions.

Today • ISEE Reading Comprehension

The ISEE Middle Level exam includes six passages, and many questions test whether you can select evidence that supports a claim.

The big question we need to answer is simple: How do you find the exact part of a passage that proves a claim? Let's learn the skills and strategies that will help you nail these questions every time.

SECTION 2

Core Principles: Claims, Evidence, and the Link Between Them

Before you can find evidence, you need to understand three key ideas. Think of them like the pieces of a puzzle. When all three fit together, you have a strong answer.

1

The Claim

A claim is the author's main point, argument, or conclusion. It is what the author wants you to believe. Example: "Recycling helps protect the environment."
2

The Evidence

Evidence is a specific fact, detail, example, or quotation from the passage that proves the claim. It is the "proof" you can point to in the text.
3

The Link

The link is the logical connection between the claim and the evidence. Ask yourself: "Does this detail directly prove that claim?" If yes, you've found the link.
4

Distractors

Distractors are wrong answer choices that mention the passage but do NOT prove the specific claim. They might be true details that support a different point.
✦

KEY TAKEAWAY

Think of a claim like a basketball player saying, "I'm the best free-throw shooter on the team." The evidence is their stats — maybe they made 90 out of 100 free throws. The link is the logic: making 90% proves you are the best. On the ISEE, wrong answers are like showing someone else's scoring stats — true information, but not proof of that specific claim.

SECTION 3

Seeing How Evidence Connects to a Claim

The diagram below shows how a claim sits at the top and different details from a passage sit below it. Only one detail directly supports the claim. The others are distractors — they come from the passage, but they prove something else.

CLAIM"Recycling helps protect the environment."DISTRACTOR A"Many cities now haveblue recycling bins."(True detail, but doesn't prove it HELPS)✓ CORRECT EVIDENCE"Recycling one ton of papersaves 17 trees from being cut."(Directly proves recycling helps)DISTRACTOR B"Recycling became popularin the 1970s."(History of recycling, not proof it helps)THE TEST: Does this detail DIRECTLY prove the claim?If the answer is YES → that's your evidence. If NO → it's a distractor.💡 ISEE TIP: Always re-read the claim BEFORE scanning answer choices.This keeps the claim fresh in your mind so you don't fall for distractors.
The diagram shows a claim at the top with three possible answer choices below. Only the center choice directly proves the claim. The other two are distractors — details that appear in the passage but do not support this specific point.

Notice how all three details come from the passage. They are all true. But only one of them actually proves the specific claim. That's the trick on the ISEE — the wrong answers are not silly or obviously wrong. They are real details from the passage that just don't match the claim in the question.

SECTION 4

The Four-Step Evidence Strategy

On the ISEE, you don't have a lot of time. You need a quick, reliable method to find the right evidence. Follow these four steps every time you see an evidence question.

1

Read the Claim Carefully

Underline or highlight the claim in the question. What exactly does it say? Break it into simple words: who, what, why?
2

Predict Before You Peek

Before reading the answer choices, think about what kind of detail would prove the claim. This stops distractors from tricking you.
3

Scan and Match

Read each answer choice and ask: "Does this detail directly prove the claim?" If not, cross it out using process of elimination.
4

Double-Check the Winner

Re-read your chosen answer alongside the claim. They should fit together like a lock and key. If the link feels weak, try again.
💡

ISEE Test-Taking Tip

There is no penalty for wrong answers on the ISEE. Even if you're unsure, always pick an answer! Use process of elimination to remove choices that clearly don't match the claim. Then guess from the remaining options.

The most important step is Step 2 — predicting before you peek. When you form your own idea of what the evidence should look like, the correct answer usually jumps out at you. Without a prediction, all four choices can seem equally tempting.

SECTION 5

Types of Evidence You'll See on the ISEE

ISEE passages use different kinds of evidence to support claims. Knowing these types will help you spot what you're looking for more quickly.

TYPES OF EVIDENCE ON THE ISEE📊 FACTS & STATSNumbers, dates, ormeasurements that provesomething is true."Temperatures rose 2°F."📖 EXAMPLESSpecific instances thatillustrate a generalclaim the author makes."For instance, eagles..."💬 QUOTATIONSDirect words from anexpert or character thatback up the point."Dr. Lee stated that..."🔍 DESCRIPTIONSSensory details or vividlanguage that shows ratherthan just tells."The barren field stretched..."⚡ CAUSE & EFFECTThe passage explains howone event led to another,proving a connection."Because of the drought..."🎯 MATCHING STRATEGYStep 1: Identify the claim type (opinion, fact, conclusion).Step 2: Look for the evidence type that best PROVES that kind of claim.Example: A claim about environmental damage → look for facts, stats, or cause-and-effect details.
Five common evidence types found in ISEE passages. When you identify the kind of claim in the question, think about which evidence type would best prove it.

On the actual ISEE, you might see a science passage that uses facts and statistics as evidence, or a fiction passage where a character's actions serve as an example of a personality trait. Being able to recognize these types will speed you up and boost your accuracy.

SECTION 6

Worked Example: Finding Evidence Step by Step

Let's walk through a sample ISEE-style question from start to finish. Read the short passage below, then follow each step.

ℹ

Sample Passage

Honeybees play a vital role in agriculture. Without them, many of the fruits and vegetables people enjoy would become scarce. According to the U.S. Department of Agriculture, honeybees pollinate approximately 80 percent of all flowering crops in the United States. In recent years, however, bee populations have declined sharply. Scientists believe that pesticides, habitat loss, and disease are the main causes. Farmers have begun planting wildflower strips along their fields to give bees safe feeding areas.

Question: Which detail from the passage best supports the claim that honeybees are important to farming?

(A) Scientists believe that pesticides, habitat loss, and disease are the main causes of bee decline. (B) Honeybees pollinate approximately 80 percent of all flowering crops in the United States. (C) Farmers have begun planting wildflower strips along their fields. (D) In recent years, bee populations have declined sharply.

Step-by-Step Solution

  1. 1

    Step 1 — Read the Claim Carefully

    The claim is that "honeybees are important to farming." Underline the key words: important and farming. We need a detail that shows bees matter to agriculture.
  2. 2

    Step 2 — Predict Before You Peek

    What kind of detail would prove bees are important to farming? Probably something about what bees DO for crops — like pollination or food production.
  3. 3

    Step 3 — Scan and Match

    Choice A talks about why bees are declining — that's a different topic. Choice B says bees pollinate 80% of flowering crops — that directly shows their importance! Choice C is about what farmers are doing — a response, not proof of importance. Choice D tells us populations are dropping — again, decline, not importance.
  4. 4

    Step 4 — Double-Check the Winner

    Claim: bees are important to farming. Evidence: they pollinate 80% of crops. Does the evidence prove the claim? Yes! If bees handle 80% of pollination, they are clearly very important.
    Answer: (B)

SECTION 7

Common Traps and How to Avoid Them

The ISEE is designed to test your thinking, so the wrong answers are often very tempting. Here are the most common traps students fall into — and how to dodge them.

TrapWhat It Looks LikeHow to Beat It
True but Off-TopicThe detail is in the passage, but it supports a different claim.Always check: Does this prove THIS specific claim?
Too GeneralThe choice repeats the claim in different words instead of giving a new, specific detail.Evidence should add new info, not just rephrase the claim.
Related TopicThe detail is about the same subject but answers a different question (cause vs. effect, for example).Ask: Does this detail answer WHY, HOW, or WHAT the claim states?
Outside KnowledgeA choice sounds right based on what you already know, but is NOT stated in the passage.Only use what is written in the passage. The answer is always in the text.

Four common wrong-answer traps on ISEE evidence questions

✦

KEY TAKEAWAY

Think of evidence questions like a detective solving a case. The detective doesn't just need a clue from the crime scene — they need the right clue that connects directly to the suspect. A fingerprint on a random cup doesn't prove anything, but a fingerprint on the safe that was robbed? That's real evidence. Match your detail to the specific claim.

SECTION 8

Evidence Skills Beyond the ISEE

Selecting evidence is not just an ISEE skill — it's a skill you'll use in high school, college, and beyond. Here's how this concept grows with you.

ISEE Middle LevelHigh School & Beyond
Find a detail from the passage that supports a given claim.Evaluate whether evidence is strong enough to prove a complex argument.
Choose from four answer options.Find and cite evidence in your own essays without pre-set choices.
Work with one passage at a time.Compare evidence across multiple sources to form an argument.
Evidence is stated directly in the text.Evidence may need to be inferred or interpreted from data, graphs, or interviews.

How evidence skills grow from the ISEE to advanced academics

For now, focus on what the ISEE asks: find the one detail in the passage that directly proves the claim. Master this, and you'll have a head start on tougher reading challenges in the future.

SECTION 9

Practice Problems

Read each short passage carefully, then answer the question that follows. Remember: use the four-step strategy — read the claim, predict, scan and match, and double-check!

Question 1: CONCEPTUAL

Read the passage. "Dogs are often called 'man's best friend' because of their loyal nature. Studies show that dogs can sense when their owners are sad and will stay close to comfort them. Dogs have been working alongside humans for over 15,000 years. There are more than 300 recognized dog breeds today." Which detail from the passage best supports the claim that dogs are loyal to their owners?
  • A. There are more than 300 recognized dog breeds today.
  • B. Dogs have been working alongside humans for over 15,000 years.
  • C. Studies show that dogs can sense when their owners are sad and will stay close to comfort them.
  • D. Dogs are often called 'man's best friend.'
Show answer (C)
The claim is that dogs are loyal. Choice C is correct because sensing an owner's sadness and staying close to comfort them is a direct example of loyalty. Choice A is about the number of breeds, which has nothing to do with loyalty. Choice B is about how long dogs have worked with humans, which shows a long relationship but not loyalty specifically. Choice D just restates the nickname without giving specific proof of loyalty.

Question 2: BASIC

Read the passage. "The Amazon rainforest is one of the most biodiverse places on Earth. Scientists have discovered more than 40,000 plant species, 1,300 bird species, and 3,000 types of fish living there. The Amazon River itself carries more water than any other river in the world. Many indigenous communities have lived in the rainforest for centuries." Which detail from the passage best supports the claim that the Amazon rainforest has a wide variety of living things?
  • A. Many indigenous communities have lived in the rainforest for centuries.
  • B. The Amazon River carries more water than any other river in the world.
  • C. The Amazon rainforest is one of the most biodiverse places on Earth.
  • D. Scientists have discovered more than 40,000 plant species, 1,300 bird species, and 3,000 types of fish living there.
Show answer (D)
The claim is about a wide variety of living things (biodiversity). Choice D is correct because it gives specific numbers of plant, bird, and fish species — this is concrete evidence of variety. Choice A is about indigenous communities, which are people, not evidence of biological diversity. Choice B is about the river's water volume, not living things. Choice C simply restates the claim using the word 'biodiverse' — it is the claim itself, not evidence that supports it.

Question 3: INTERMEDIATE

Read the passage. "Clara Barton showed remarkable courage throughout her life. During the Civil War, she traveled to battlefields to nurse wounded soldiers, often while bullets were still flying overhead. After the war, she founded the American Red Cross. Barton led the organization for 23 years, personally directing relief efforts during floods, hurricanes, and other disasters. She was also an early supporter of women's rights." Which detail from the passage best supports the claim that Clara Barton was personally brave?
  • A. She founded the American Red Cross.
  • B. She traveled to battlefields to nurse wounded soldiers while bullets were still flying.
  • C. She was an early supporter of women's rights.
  • D. She led the organization for 23 years.
Show answer (B)
The claim is about personal bravery. Choice B is correct because going to battlefields while bullets are flying is a direct, specific example of physical courage. Choice A shows leadership and initiative, but founding an organization doesn't necessarily require bravery. Choice C is about supporting women's rights, which is admirable but doesn't specifically demonstrate bravery. Choice D shows dedication and commitment, but leading an organization for many years is about persistence, not courage in the face of danger.

Question 4: APPLIED

Read the passage. "Sleep is essential for students who want to do well in school. Research from the National Sleep Foundation shows that teenagers who get fewer than seven hours of sleep per night score an average of 10 points lower on tests than students who sleep eight or more hours. During sleep, the brain processes and stores the information learned during the day. Many schools have begun pushing back start times to 8:30 a.m. to allow students more rest. Despite these efforts, most teens still report feeling tired during morning classes." Which detail from the passage best supports the claim that lack of sleep hurts academic performance?
  • A. Many schools have begun pushing back start times to 8:30 a.m.
  • B. Most teens still report feeling tired during morning classes.
  • C. Teenagers who get fewer than seven hours of sleep score an average of 10 points lower on tests.
  • D. During sleep, the brain processes and stores information learned during the day.
Show answer (C)
The claim is that lack of sleep hurts academic performance. Choice C is correct because it gives a specific statistic linking less sleep to lower test scores — that directly shows poor sleep hurting grades. Choice A describes a solution schools are trying, not evidence of the problem. Choice B says teens feel tired, which is about how they feel, not about academic performance specifically. Choice D explains what the brain does during sleep, which is a mechanism, but it doesn't show that less sleep actually hurts performance. The key difference is that C shows a measurable result.

Question 5: CRITICAL THINKING

Read the passage. "When Maria moved to a new city, she felt like an outsider. The other students at her school had known each other since kindergarten, and they already had their own groups of friends. At lunch, Maria sat alone at the end of a long table, watching the others laugh and share stories. One afternoon, the art teacher asked students to work in pairs on a mural project. A girl named Jess chose Maria as her partner. Over the following weeks, Maria and Jess spent hours painting side by side. They discovered that they both loved graphic novels and soccer. By the end of the project, Maria finally felt like she belonged." Which detail from the passage best supports the claim that the mural project helped Maria feel less isolated?
  • A. The other students had known each other since kindergarten.
  • B. At lunch, Maria sat alone at the end of a long table.
  • C. The art teacher asked students to work in pairs on a mural project.
  • D. Over the following weeks, Maria and Jess spent hours painting side by side and discovered shared interests.
Show answer (D)
The claim is that the mural project helped Maria feel less isolated. Choice D is correct because it shows what happened during the project — Maria and Jess spent time together and found common interests, which is exactly how someone stops feeling isolated. Choice A explains why Maria felt like an outsider, which is background information, not proof the project helped. Choice B shows Maria's loneliness before the project, which is the opposite of what the claim is about. Choice C only describes the teacher assigning the project — it's the setup, not evidence that the project actually helped Maria. This question is tricky because choices A and B relate to the same theme of isolation, but they describe the problem, not the solution.

SUMMARY

Putting It All Together

Summary

On the ISEE, evidence questions ask you to find the specific detail in a passage that proves a claim. Remember the four-step strategy: read the claim carefully, predict before you peek at the answer choices, scan and match using process of elimination, and double-check that your answer directly proves the claim.

Watch out for distractors — wrong answers that are true details from the passage but don't support the specific claim in the question. The five common evidence types are facts and statistics, examples, quotations, descriptions, and cause-and-effect details. Always ask yourself one simple question: "Does this detail DIRECTLY prove the claim?" If the answer is yes, you've found your evidence. And remember — there's no penalty for guessing, so always answer every question!
